<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available
In general, warmer and wetter biomes have higher net primary productivity than colder and drier biomes. The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>
The cane toad was a failure as a biological control method in Australia because:
-The greyback beetle it was supposed to be eating fed at the top of the sugarcane stalks (which were 6-8 meters in height). Cane toads cannot fly or climb and therefore couldnt feed on the beetles.
-The beetles were out during the daytime, and cane toads feed at night.
-The two species are not seasonally compatible (aren't in the same place at the same time of year).
-The toads needed moist conditions to survive, and so moved away from where they were supposed to be.
-The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives.
-Breeding habits made the cane toads a very invasive species.
Least dense to most dense: gas, solid, liquid.
They are called a population, because they are the same species living in a given area. The word population means the amount of a certain species living in a certain environment.
